Building a new home or adding on to your existing one? San Gregorio Roofing & Maintenance handles new roof installation from decking to ridge cap. We work with your general contractor or architect to coordinate scheduling, material selection, and code compliance for your San Gregorio build.
Material options include architectural asphalt shingles, standing seam metal, corrugated metal, and flat membrane systems. Each has different pros, cons, and price points. We help you choose based on your budget, aesthetic preferences, the pitch of your roof, and the climate demands of CA.
Our New Roof Installation Process
Plan Review & Consultation
Meet with our San Gregorio project coordinator to select materials, review color options, and confirm the installation scope. We work with your GC or architect to ensure the roof spec meets the overall building design.
Preparation
All materials verified against your approved proposal. Color, brand, quantity, everything double-checked before install day. No substitutions without your approval.
Certified Installation
From underlayment to ridge cap, every layer installed in the correct sequence by certified crews. A project manager is on-site for new construction installs to ensure quality at every stage.
Inspection & Warranty
Final quality check against manufacturer installation requirements. Building inspection coordinated through our San Gregorio office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.
